Lithogenous sediments come from the land They result primarily from erosion by water, wind, and ice Biogenous sediments originate from organisms The particles in these sediments come from shells and hard skeletons. Although lithogenous sediments represent the largest total volume, biogenous sediments cover a greater area of sea floor
Lithogenous sediment is the most common neritic deposit because it is primarily derived from the erosion and weathering of rocks on land. These sediments are transported to the ocean by rivers and wind, accumulating in shallow continental shelf areas where neritic deposits are found. This continuous process of erosion and transportation ensures a steady supply of lithogenous sediment to neritic environments.
Lithogenous sediment is made up of fragments of rocks and minerals that have been eroded and transported by various geological processes before settling on the ocean floor. These sediments typically originate from continental sources and can include materials such as quartz, feldspar, and clay minerals. Lithogenous sediment forms a significant component of marine sedimentary deposits.
Sediments produced by plants and animals in the sea are called biogenic sediments. These sediments are composed of organic remains, such as shells, corals, and skeletal debris, which accumulate on the seafloor over time.
Biogenous sediments are primarily composed of the remains of marine organisms. The two main types are calcareous ooze, which is formed from the calcium carbonate shells of organisms like foraminifera and coccolithophores, and siliceous ooze, composed of silica from diatoms and radiolarians. These sediments accumulate on the ocean floor and play a crucial role in the carbon cycle and marine ecosystem dynamics.
There are two types of deep ocean sediments, abyssal clay and biogenous oozes. Abyssal clays are fine-grained sediment, while biogenous ooze is composed of the hard parts of microscopic organisms.
Lithogenous sediment is not biogenous; it originates from the erosion of rocks on land. Biogenous sediments come from the remains of living organisms, such as shells and coral. Hydrogenous sediments are chemical precipitates that form in seawater.
The three types of ocean floor sediments are Terrigenous, Biogenous, and Hydrogenous sediments.
terrigenous or continental sediments
Terrigenous sediments come from the earth "Terri" means land or earth in greek "genous" means origin. Biogenous sediments come from organic matter.

The two types of biogenous sediments are siliceous oozes, which are made up of silica-based remains of diatoms and radiolarians, and calcareous oozes, which consist of calcium carbonate shells of organisms like foraminifera and coccolithophores.

The three types of ocean floor sediments are terrigenous (derived from land sources), biogenous (derived from biological organisms), and hydrogenous (derived from chemical processes in seawater).
Ocean floor sediments primarily consist of three types: terrigenous, biogenous, and hydrogenous sediments. Terrigenous sediments originate from land, including clays and silts brought by rivers and wind. Biogenous sediments are formed from the remains of marine organisms, such as foraminifera and diatoms, while hydrogenous sediments precipitate directly from seawater, including minerals like manganese nodules. Additionally, cosmogenous sediments, derived from extraterrestrial sources like meteorites, are also present but in smaller amounts.
